Report Abuse. The collision of an oceanic plate, and a continental plate produce a plate boundary known as a subduction zone. The colder, denser [typically basaltic crust (approx. 3.3g/cm^3)] oceanic plate is forced underneath the less dense [typically granitic (d= 2.7)] continental crust.
A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate [continental plate: A section of the crust that makes up the Earth's landmasses.] .onstructive plate boundary. A constructive plate boundary, sometimes called a divergent plate margin, occurs when plates move apart. Volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed. An example of a constructive plate boundary is the mid-Atlantic Ridge.
